我们研究了人体尸体髋内收长肌 (AL) 肌肉的剪切模量与被动力关系，并使用剪切波弹性成像 (SWE) 探讨了肌肉结构对 AL 肌肉弹性特性的影响。九块 AL 肌肉是从一具经过防腐处理的柔软尸体上获取的。 AL 肌肉被固定在一个定制的装置上，该装置包括两个夹子、一个滑轮和一根电缆，以提供被动负载，这些负载以 60 克的增量从 0 克增加到 600 克。测量 AL 肌肉的近端 (Pro)、中部 (Mid) 和远端 (Dis) 区域的剪切模量。测量 AL 肌肉的质量和解剖横截面积 (ACSA)。通过拟合最小二乘回归线来分析每个测试肌肉区域的剪切模量-被动负载关系。此外，计算每单位载荷(s)的剪切模量的增加率。每个区域的所有 AL 肌肉的剪切模量和被动力均呈线性相关 (p < 0.01)。 Pro、Mid 和 Dis 的平均决定系数 (R-2) 分别为 0.989、0.986 和 0.982。每单位载荷剪切模量的增加率与肌肉质量（r = 0.77，p = 0.02）和 ACSA（r = 0.43，p = 0.03）的倒数显着相关。剪切波弹性成像可用作 AL 肌肉任何区域被动力的间接测量。此外，每单位载荷剪切模量的增加率可能与肌肉结构参数相关。
We investigated the shear modulus-passive force relationship in the hip adductor longus (AL) muscles of human cadavers and explored the effect of muscle architecture on the elastic properties of the AL muscle using shear wave elastography (SWE). Nine AL muscles were harvested from a soft, embalmed cadaver. The AL muscles were affixed to a custom-built device comprising two clamps, a pulley, and a cable to provide passive loads, which were increased from 0 to 600 g in 60-g increments. The shear modulus of the AL muscle was measured in the proximal (Pro), middle (Mid), and distal (Dis) regions. The masses and anatomical cross-sectional areas (ACSAs) of the AL muscles were measured. The shear modulus-passive load relationship of each tested muscle region was analyzed by fitting a least-squares regression line. Moreover, the rate of increase in the shear modulus per unit load (s) was calculated. The shear modulus and passive force were linearly correlated for all AL muscles in each region (p < 0.01). The mean coefficients of determination (R-2) for Pro, Mid, and Dis were 0.989, 0.986, and 0.982, respectively. The rate of increase in the shear modulus per unit load significantly correlated with the reciprocal of the muscle mass (r = 0.77, p = 0.02) and ACSA (r = 0.43, p = 0.03). Shear wave elastography can be used as an indirect measure of passive force in any region of the AL muscle. Additionally, the rate of increase in the shear modulus per unit load could be associated with muscle architectural parameters.
